When the ventilation unit 20a and the ventilation unit 20b are not distinguished, they are collectively referred to as "ventilation unit 20", and when the sterilization unit 22a and the sterilization unit 22b are not distinguished, they are collectively referred to as "sterilization unit 22".

Space 10 is a space that is a target of ventilation and sterilization, and is a space that is a target of cleaning by a worker (a target of housekeeping by a chambermaid). The space 10 is, for example, a room (guest room) of an accommodation facility such as a hotel. Here, two of the first space 10a and the second space 10b are shown as the plurality of spaces 10, but the number of spaces 10 is not limited.

The first space 10a is provided with a ventilation unit 20a and a sterilization unit 22a. The second space 10b is provided with a ventilation unit 20b and a sterilization unit 22b.

In addition, although not particularly shown, in the first space 10a and the second space 10b, individual air conditioning systems, table sets, beds, wash basins, unit baths, toilets, televisions, refrigerators, etc. are provided so that customers can spend their time comfortably. Equipment may be installed to make the customer feel comfortable. In addition, amenity goods such as shampoos, soaps, toothbrushes, razors, combs, shower caps and cosmetics may be prepared in the first space 10a and the second space 10b.

The ventilation unit 20 is installed on the ceiling surface of the space 10 and can ventilate the air from the space 10 to the outside. As the ventilation unit 20, a known ventilation device can be adopted. The ventilation unit 20 is connected to the control unit 50 so as to be able to communicate by wire or wirelessly, and operates or stops according to an output signal from the control unit 50.

More specifically, the ventilation unit 20a is installed on the ceiling surface of the first space 10a, and ventilates the first space 10a based on the output signal from the control unit 50. Further, the ventilation unit 20b is installed on the ceiling surface of the second space 10b, and ventilates the second space 10b based on the output signal from the control unit 50.

The sterilization unit 22 is an air purification unit installed on the ceiling surface of the space 10, and a predetermined sterilization component (for example, hypochlorous acid) is added to the air supplied to the space 10 and released. Then, the sterilization unit 22 sterilizes the space 10 with the air to which the sterilization component is added, in other words, purifies the space 10. The sterilization component can also be said to be an air purification component. The sterilization unit 22 is connected to the control unit 50 by wire or wirelessly, and operates or stops according to an output signal from the control unit 50.

More specifically, the sterilization unit 22a is installed on the ceiling surface of the first space 10a, and sterilizes the inside of the first space 10a based on the output signal from the control unit 50. Further, the sterilization unit 22b is installed on the ceiling surface of the second space 10b, and sterilizes the inside of the second space 10b based on the output signal from the control unit 50.

The mobile terminal 30 is an information processing terminal that can be carried by a worker who performs cleaning work (for example, housekeeping work) in the space 10, and is, for example, a smartphone or a tablet terminal. The mobile terminal 30 can wirelessly communicate with the control unit 50, can acquire room information from the control unit 50, and can transmit work information to the control unit 50. Here, the guest room information acquired from the control unit 50 is, for example, usage information of the space 10 (information regarding a used state or an unused state) or purification processing in the space 10 (second purification control or third purification described later). Includes information such as completion notification of purification processing based on control). Further, the work information transmitted to the control unit 50 includes information such as a scheduled start time of the cleaning work of the space 10 or a notification of the completion of the cleaning work. In the embodiment of the present disclosure, a mobile terminal 30 that can be carried as an information processing terminal is exemplified, but the present invention is not limited to this. For example, the information processing terminal may be a stationary information processing terminal installed at the front desk of a hotel, a room where a worker waits, or the like. The stationary information processing terminal can communicate with the control unit 50 wirelessly or by wire.

The reception unit 40 receives usage information of the customer's space 10 input to the customer management system (not shown) of the accommodation facility. Here, the usage information includes information regarding whether or not the guest room is used by the customer. Whether or not the guest room is used is shown as "used state" when the customer checks in to the guest room, and is shown as "unused state" when the customer checks out the guest room.

Then, the reception unit 40 is connected to the control unit 50 so as to be able to communicate by wire or wirelessly, and transmits the usage information of the space 10 to the control unit 50. More specifically, when the customer checks in to the reserved first space 10a, the first space 10a becomes "used state". If the customer checks out the first space 10a, the first space 10a becomes "unused". The reception unit 40 transmits such usage information of the first space 10a to the control unit 50. The same applies to the second space 10b. The reception unit 40 may be the customer management system itself.

The control unit 50 is an information processing unit that controls each operation of ventilation and sterilization in the space purification system 100. That is, the control unit 50 controls the operation of the ventilation unit 20 installed in the space 10 and the operation of the sterilization unit 22 installed in the space 10. More specifically, the control unit 50 controls the operations of the ventilation unit 20a and the sterilization unit 22a installed in the first space 10a. Further, the control unit 50 controls the operations of the ventilation unit 20b and the sterilization unit 22b installed in the second space 10b.

Next, the control unit 50 will be described in detail with reference to FIG. FIG. 2 is a block diagram showing a configuration of a control unit 50 in the space purification system 100.

As shown in FIG. 2, the control unit 50 includes an input unit 50a, a processing unit 50b, an output unit 50c, a storage unit 50d, and a timing unit 50e.

The input unit 50a receives the usage information of each of the plurality of spaces 10 output from the reception unit 40 and the work information output from the mobile terminal 30. The input unit 50a outputs the received usage information and work information to the processing unit 50b.

The storage unit 50d stores data referenced or updated by the processing unit 50b. For example, the storage unit 50d stores an algorithm for determining the operation mode of the first purification control executed by the ventilation unit 20 and the sterilization unit 22 when the space 10 is in the “use state”. Further, the storage unit 50d stores an algorithm for determining the operation mode of the second purification control executed by the ventilation unit 20 and the sterilization unit 22 when the space 10 changes from the “used state” to the “unused state”. ing. Further, the storage unit 50d stores an algorithm for determining the operation mode of the third purification control executed by the ventilation unit 20 and the sterilization unit 22 when the cleaning work in the space 10 by the operator is completed.

The first purification control is a control executed by the ventilation unit 20 and the sterilization unit 22 when the space 10 is in the "use state". Even if the first purification control is executed in conjunction with the air conditioning control by an air conditioner (not shown) for adjusting the air quality (for example, temperature, humidity, air volume, fragrance, etc.) specified by the customer using the space 10. good.

The second purification control is the first as a countermeasure against infection by bacteria or viruses that may remain in the space 10 due to the customer when the space 10 changes from the "used state" to the "unused state". It is a control executed by increasing the ventilation volume of the ventilation unit 20 and the sterilization component amount of the sterilization unit 22 rather than the purification control. In the second purification control, it is preferable that the air conditioning control by the air conditioning device is stopped.

The third purification control is based on the first purification control as a countermeasure against infection by bacteria or viruses that may remain in the space 10 due to the worker when the cleaning work in the space 10 by the worker is completed. Is also a control executed by increasing the ventilation volume of the ventilation unit 20 and the amount of the sterilizing component of the sterilizing unit 22. In the third purification control, it is preferable that the air conditioning control of the air conditioner is stopped.

Then, the storage unit 50d outputs the stored data (storage data) to the processing unit 50b in response to a request from the processing unit 50b.

The timekeeping unit 50e is used to measure the time as needed in the program executed by the processing unit 50b. Then, the timekeeping unit 50e outputs data (time data) indicating the current time to the processing unit 50b.

The processing unit 50b receives usage information and work information output from the input unit 50a, storage data output from the storage unit 50d, and time data output from the timekeeping unit 50e. The processing unit 50b uses each received information (usage information, work information, storage data, and time data) to control the ventilation operation of the ventilation unit 20 and the sterilization operation of the sterilization unit 22 in each of the plurality of spaces 10. Identify the information. The program executed by the processing unit 50b may be a program recorded on a recording medium such as a memory card and provided, or a program provided through a telecommunication line such as the Internet may be used. .. Then, the processing unit 50b outputs the specified control information to the output unit 50c.

The output unit 50c outputs the control information output from the processing unit 50b to the ventilation unit 20 and the sterilization unit 22. Further, the output unit 50c outputs information (completion information) regarding the completion of the second purification control to the mobile terminal 30 based on the completion time information of the second purification control included in the control information. The mobile terminal 30 to which the output unit 50c outputs the completion information may be the mobile terminal 30 that outputs the work information to the input unit 50a, and is different from the mobile terminal 30 that outputs the work information to the input unit 50a. It may be a mobile terminal 30.

Then, the ventilation unit 20 executes the ventilation operation according to the control information output from the output unit 50c. Further, the sterilization unit 22 executes the sterilization operation according to the control information output from the output unit 50c. Then, the mobile terminal 30 notifies the operator that the second purification control is completed by displaying the completion information output from the output unit 50c or the like.

As described above, the control unit 50 causes the ventilation unit 20 and the sterilization unit 22 to execute each operation of the first purification control to the third purification control.

Next, with reference to FIGS. 3 and 4, the first operation control to the third operation control by the control unit 50 related to the housekeeping work will be described. 3 and 4 are flowcharts showing the operation of the control unit 50.

(Operation control until the start of housekeeping work)
First, with reference to FIG. 3, the operation control by the control unit 50 until the worker starts the cleaning work (housekeeping work) in the first space 10a will be described by taking the first space 10a as an example.

If the customer checks in to the reserved guest room of the first space 10a at the front desk of the accommodation facility, the usage information of the first space 10a becomes "used state". At this time, as shown in FIG. 3, the control unit 50 causes the ventilation unit 20a and the sterilization unit 22a to execute an operation based on the first purification control (step S01). At this time, the control unit 50 is linked to the first purification control, and the air conditioning (not shown) is adjusted so as to adjust the air quality (for example, temperature, humidity, air volume, fragrance, etc.) specified by the customer using the first space 10a. The device may be made to perform air conditioning control.

After that, the control unit 50 periodically acquires usage information of the first space 10a from the reception unit 40 (step S02).

Then, the control unit 50 changes from the "used state" to the "unused state" whether or not the customer who used the first space 10a has checked out, that is, the usage information of the first space 10a acquired from the reception unit 40. It is determined whether or not the change has occurred (step S03).

When the control unit 50 determines that the "used state" has not changed to the "unused state" as a result of the determination in step S03, that is, when it is determined that the "used state" remains (No in step S03). To continue the operation based on the first purification control for the ventilation unit 20a and the sterilization unit 22a (return to step S01). On the other hand, when the control unit 50 determines that the "used state" has changed to the "unused state" (Yes in step S03), the control unit 50 refers to the ventilation unit 20a and the sterilization unit 22a. The operation based on the second purification control is executed (step S04).

Then, the control unit 50 determines whether or not the time measured from the start time of the operation based on the second purification control in step S04 has elapsed a certain time (first time T1) (step S05). ).

When the control unit 50 determines as a result of the determination in step S05 that the first time T1 has not elapsed (No in step S05), the operation based on the second purification control is continued as it is (in step S05). return). On the other hand, when the control unit 50 determines that the first time T1 has elapsed (Yes in step S05), the control unit 50 ends the operation based on the second purification control and restarts the operation based on the first purification control (step). S06). Here, the first time T1 is set to, for example, 10 minutes.

Subsequently, the control unit 50 notifies the mobile terminal 30 of the completion of the purification process (purification process by the second purification control) of the first space 10a (step S07).

After that, the worker carrying the mobile terminal 30 that has received the notification of the completion of the purification process of the first space 10a moves to the first space 10a and starts the cleaning work (housekeeping work) in the first space 10a.

The above is the operation control by the control unit 50 until the housekeeping work is started.

(Operation control after starting housekeeping work)
Next, with reference to FIG. 4, operation control by the control unit 50 after the worker starts the cleaning work (housekeeping work) in the first space 10a will be described.

As shown in FIG. 4, the control unit 50 causes the ventilation unit 20a and the sterilization unit 22a to execute an operation based on the first purification control, continuing from step S06 in FIG. 3 (step S11). As a result, the worker performs the cleaning work under the condition that the ventilation operation of the ventilation unit 20a and the sterilization operation of the sterilization unit 22a are performed based on the first purification control. After that, when the cleaning work in the first space 10a is completed, the worker inputs the work end information to the mobile terminal 30 and moves to another space 10 (for example, the second space 10b) to be cleaned.

Then, the control unit 50 determines whether or not the work end information (cleaning work completion notification) has been acquired from the mobile terminal 30 (step S12).

When the control unit 50 determines that the work end information has not been acquired from the mobile terminal 30 as a result of the determination in step S12 (No in step S12), the control unit 50 determines that the ventilation unit 20a and the sterilization unit 22a are used. The operation based on the first purification control is continued (returning to step S11). On the other hand, when the control unit 50 determines that the work end information has been acquired (Yes in step S12), the control unit 50 causes the ventilation unit 20a and the sterilization unit 22a to execute an operation based on the third purification control (step). S13).

Then, the control unit 50 determines whether or not the time measured from the start time of the operation based on the third purification control in step S13 has elapsed a certain time (second time T2) (step S14). ).

When the control unit 50 determines as a result of the determination in step S14 that the second time T2 has not elapsed (No in step S14), the operation based on the third purification control is continued as it is (in step S14). return). On the other hand, when the control unit 50 determines that the second time T2 has elapsed (Yes in step S14), the control unit 50 ends the operation based on the third purification control and restarts the operation based on the first purification control (step). S15). Here, the second time T2 is set to, for example, 10 minutes.

Subsequently, the control unit 50 notifies the mobile terminal 30 of the completion of the purification process of the first space 10a (purification process by the third purification control) (step S16). As a result, the operator can recognize that the purification treatment of the first space 10a has been completed.

The above is the operation control by the control unit 50 after the housekeeping work is started.

(Characteristics of space purification system 100)
As described above, in the space purification system 100, before and after the cleaning work in the first space 10a, ventilation and ventilation by the ventilation unit 20a and the sterilization unit 22a are performed based on the second purification control and the third purification control, respectively. Sterilization is done.

[Modification example]
Next, a modified example of the operation control by the control unit 50 will be described with reference to FIG. FIG. 5 is a flowchart showing a modified example of the operation control by the control unit 50.

If the customer checks in to the reserved guest room of the first space 10a at the front desk of the accommodation facility, the usage information of the first space 10a becomes "used state". At this time, as shown in FIG. 5, the control unit 50 causes the ventilation unit 20a and the sterilization unit 22a to execute an operation based on the first purification control (step S21).

After that, the control unit 50 periodically acquires usage information of the first space 10a from the reception unit 40 (step S22).

Then, the control unit 50 changes from the "used state" to the "unused state" whether or not the customer who used the first space 10a has checked out, that is, the usage information of the first space 10a acquired from the reception unit 40. It is determined whether or not the change has occurred (step S23).

When the control unit 50 determines that the "used state" has not changed to the "unused state" as a result of the determination in step S23, that is, when it is determined that the "used state" remains (No in step S03). To continue the operation based on the first purification control for the ventilation unit 20a and the sterilization unit 22a (return to step S21). On the other hand, when the control unit 50 determines that the "used state" has changed to the "unused state" (Yes in step S23), the control unit 50 enters the standby state (step S24). In this standby state, the control unit 50 continues the operation based on the first purification control.

After that, the control unit 50 determines whether or not the cleaning work start time information (information regarding the scheduled start time of the cleaning work) has been acquired from the mobile terminal 30 (step S25).

When the control unit 50 determines that the start time information has not been acquired from the mobile terminal 30 as a result of the determination in step S25 (No in step S25), the control unit 50 continues the standby state (returns to step S24). On the other hand, when the control unit 50 determines that the start time information has been acquired (Yes in step S25), the control unit 50 ventilates and sterilizes the first space 10a by the start time of the cleaning work based on the start time information. The ventilation unit 20a and the sterilization unit 22a are made to perform an operation based on the second purification control so as to be completed (step S26).

Then, the control unit 50 determines whether or not the time measured from the start time of the operation based on the second purification control in step S26 has elapsed a certain time (third time T3) (step S27). ).

When the control unit 50 determines as a result of the determination in step S27 that the third time T3 has not elapsed (No in step S27), the operation based on the second purification control is continued as it is (in step S27). return). On the other hand, when the control unit 50 determines that the third time T3 has elapsed (Yes in step S27), the control unit 50 ends the operation based on the second purification control and restarts the operation based on the first purification control (step). S28). That is, the control unit 50 completes the operation based on the second purification control according to the start time of the cleaning work. Here, the third time T3 is set to, for example, 10 minutes, like the first time T1.

After that, the worker moves to the first space 10a according to the start time of the cleaning work without receiving the notification of the completion of the purification process of the first space 10a, and the cleaning work (housekeeping work) in the first space 10a. To start.

Since the processing procedure after the worker starts the cleaning work (housekeeping work) in the first space 10a is the same as that in FIG. 4, the description thereof will be omitted.

As described above, in the space purification system 100, in the modified example of the operation control by the control unit 50, before and after the cleaning work in the first space 10a, based on the second purification control and the third purification control, respectively. Ventilation and sterilization are performed by the ventilation unit 20a and the sterilization unit 22a.

In the space purification system 100, similarly, in the other spaces 10 including the second space 10b, before and after the cleaning work of the space 10 to be cleaned, based on the second purification control and the third purification control, respectively. , Ventilation and sterilization are performed by the ventilation unit 20 and the sterilization unit 22.

According to such a configuration, the worker can start the cleaning work in the space 10 (for example, the housekeeping work in the guest room) after the completion of the second purification control in which the ventilation volume and the sterilization component amount are increased. As a result, the space 10 is ventilated and sterilized, so that the worker can perform the cleaning work in a safe and secure state. That is, in the space purification system 100, it is possible to improve the countermeasures against infection by bacteria or viruses in the room cleaning work by the worker.

(2) In the space purification system 100, the control unit 50 can communicate with the mobile terminal 30 that receives the information of the space 10 or transmits the work information for the space 10, and the control unit 50 is in the first time T1. After that, information regarding the completion of the second purification control may be output to the mobile terminal 30.

According to such a configuration, the worker carrying the mobile terminal 30 performs cleaning work (for example, housekeeping work in the guest room) in the space 10 after the completion of the second purification control in which the ventilation volume and the sterilization component amount are increased. You can start. As a result, the space 10 is ventilated and sterilized, so that the worker can perform the cleaning work in a safe and secure state. That is, in the space purification system 100, it is possible to improve the countermeasures against infection by bacteria or viruses in the room cleaning work by the worker.

(3) In the space purification system 100, the control unit 50 can communicate with the mobile terminal 30 that receives the information of the space 10 or transmits the work information for the space 10, and the control unit 50 uses the usage information. When the state is changed from the unused state to the unused state and the information regarding the start time of the cleaning work is input to the mobile terminal 30, the second purification control may be executed for the first time T1.

According to such a configuration, it is possible to complete the second purification control in which the ventilation volume and the sterilization component amount are increased with respect to the space 10 by the time immediately before the worker starts the cleaning work of the space 10. As a result, the worker can perform the cleaning work in a safer and more secure state.

(4) In the space purification system 100, when the information regarding the completion of the cleaning work is input to the mobile terminal 30, the control unit 50 adds the ventilation volume by the ventilation unit 20 and the sterilization unit 22 rather than the first purification control. The third purification control in which the amount of the sterilizing component to be sterilized may be increased for the second time T2 may be executed.

According to such a configuration, after the cleaning work by the worker is completed, the third purification control with increased ventilation volume and sterilization component amount is executed for the space 10. This makes it possible to provide the space 10 to a user (for example, a customer) who uses the space 10 after the cleaning work is completed in a safe and secure state in which ventilation and sterilization are performed.

(5) The space purification system 100 adds a sterilizing component to the portable terminal 30 carried by the worker who performs the cleaning work in the space 10, the ventilation unit 20 for ventilating the space 10, and the air conveyed to the space 10. It includes an additional sterilization unit 22, a reception unit 40 that receives information on the use of the space 10 by the user, and a control unit 50 that controls the operation of the ventilation unit 20 and the sterilization unit 22. The control unit 50 is performed by the ventilation unit 20 and the sterilization unit 22 when the usage information received by the reception unit 40 changes from the "used state" to the "unused state" and the usage information is in the "used state". The second purification control in which the ventilation volume by the ventilation unit 20 and the amount of the sterilizing component added by the sterilizing unit 22 are increased rather than the first purification control is executed for the first hour T1. Information (completion notification) regarding the completion of the second purification control is output to the mobile terminal 30.

By doing so, the worker carrying the mobile terminal 30 can perform cleaning work (for example, in the guest room) in the space 10 to be cleaned after the completion of the second purification control in which the ventilation volume and the amount of the sterilizing component are increased. Housekeeping work) can be started. As a result, the space 10 is ventilated and sterilized, so that the worker can perform the cleaning work in a safe and secure state. That is, in the space purification system 100, it is possible to improve the countermeasures against infection by bacteria or viruses in the cleaning work of the room (space 10) by the worker.
